The strategy closed trades at false prices. All those trades were supposed to be closed positive when the price had finally reached those levels. Why did this happen?

Most likely due to a singular price quote that met the profit targets.

I have not seen rogue price quotes yet, but heard that they happen especially with MT4 servers. Zorro has a mechanism to filter them out:

This is for the next release; in the current Zorro version, it's g->TickAvg instead of TickSmooth.
